1. A film prepared by printing an ink composition on a substrate and drying or curing the ink composition, wherein the ink composition comprises a binder material and at least one narrow band emission phosphor, the narrow band emission phosphor having a D50 particle size from about 0.1 μm to about 15 μm and is selected from the group consisting of a green-emitting U6+-containing phosphor, a green-emitting Mn2+-containing phosphor, a red-emitting phosphor based on complex fluoride materials activated by Mn4+, and a mixture thereof, wherein the ink composition has a viscosity in the range of 0.5 centipoise to 2000 centipoise.
